If the credit note is still a draft, you can delete it using the Delete button at the bottom of the page. If you already finalised the credit note, you must create another credit note for the incorrect credit note.

Create the new credit note in the same way as you did for the original invoice. This time, the amount will be positive because you are taking back the money you incorrectly credited.
